Application filed November 29, 1901. Serial No. 83,968. (No model.)

Tov all whom it may concern:

Be it known that I, WILLIAM H. SMYTH, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Can-Body Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to a cutting, endforming, and embossing machine for cylindrical can-bodies.

The object of the invention is to provide a simple and efficient device for turning the outer edges of cans slightly inward to facili.- tate the entrance of the can end into a cover or head and at the same time form on,the canbody a raised circumferential bead against which the flange of' the head may rest, also to form on the bodyv of the can any lettering or other design in raised or depressed lines or characters. y

A further objectof the invention is to provide a machine that will trim the can-body to a definite length while performing its other functions or cut vfrom a cylindrical form bodies of shorter length than the cylinder.

These objects are accomplished by lneans of the devices illustrated inv theacconipanying drawings, inV which- Figure lis a front elevation. Fig. 2 is a side elevation. Fig. 3is a detail of the motion-transmitting gearing of the rolls. Fig. 4 is a sectional elevation of the upper portion of the machine, showing the roll raising `and lowering cam and the ejector-cam. `Fig. 5 showsadetail ofamodication. Fig. 6 shows va detailof the rolls, on enlarged scale, Vwith raised or depressed designs when it is'desired to have such on the can, as is indicated in Fig. 6. Forward on this roll is a cutting and edge-forming plate c', of a widthapproxi-l mately equal to the depth of a can-head, of..

' able therein.

i as a thrust-bearing.

cutting-plate d.

Thisroll c is provided with p hardened metal having its edges slightly beveled, as shown in Figs. 2 and`6. Upon the forward end of vroll c is a slightly-raised washer c2, having an inclined lor, tapered portion extending from both of its edges.

Beneath the shaft C in the frame A are two v vertically-slidable blocks B B", carrying journal-boxes. One of these journal-boxes B3 is transversely slidable in block B to be adjust- Itis provided also with an adj usting-screw B2, journaled in it and screwed into a nut projecting downwardly from the journal-box. The journal-box of B is formed In the journal-bearings of B and B' rests'a shaft D in the same vertical plane as C. On the forward end of D is a roller d, and forward of the roll d is a 'lwo grooves d2 and ds are formed in the circumference of roll d, wider than the beads c3 ando4 of roll c, but cor- 'responding therewith center and center as to longitudinal position, as shown in Fig. 6. In the roll dis also provided designs corresponding to but raised or depressed reversely to those upon the roll c. The parts c c o2 cs c4 and d d d? d5, are each separate plates, so as tof 'provide for dierent sizes and styles of cans.

Hinged in the block Bis a link E, and a similar link E is similarly connected to block B'. Theselinks E and E are loosely connected to levers f and f', respectively, secured upon a shaft F,gjournaled in frame A. Secured upon one end of the shaft Fjis a counterweight G. Upon theshaft Dis rigidly secured a gearpinion H, and upon the shaft O is journaled a gear H', approximatelytwice the diameter of H; Attached to the side of the gear H is a' Upon the face of the cam h' A vertical 55 circumferential bead c3, and adjacent to the jonrnaled in frame A. These levers J eX- tend upwardly, their upper` ends being one on either side of the shaft C and connected to a slidable collar K slightly larger in internal diameter than the diameter of the beads cs and c, over which the collar K is adapted to move. To this collar the levers J J are loosely attached at their upper ends. The collar K slides horizontally upon pins K and K2. (Shownin end view in Figs. 1 and 4.) To return the collar K, a suitable spring K8 is attached to the lower part of lever I by one of its ends, the other end being attached to asuitable portion of the frame A, as shown in Fig. 2. Connecting the shafts C and D is a gear-train consisting of gears L, L', L3, and L8, journaled in a suitable frame, the gears L and L' being secured, respectively, upon the shafts C and D.

In operation and assuming the driving-belt to be on the tight pulley, the shafts C and D are put in rotation through their connecting train-gear L, L', L2, and L3. A can is then slipped over` the roll c, its inner end resting against the collar K. The rotation of shaft D by the intermeshing of pinion II with gear H' rotates the cam h. Thus the raised portion of cam h travels oi the cam-roll h', and the counterweight G raises the shaft D,so that the rollers c and d, which by means of the adjusting-screw B2 are accurately adjusted one to the other, come into operating engagement. Thus the cutting-plate d' trims the outer end of the can or severs it from a longer cylinder. The beads on the upper roll depress portions of the can into the grooves of the lower rolls, and the high portion of the lower roll bends the inner edge of the can in. A similar bending action on the front end of the can is caused by the cuttingplate d', owing to the beveled character of the edge of the cutting-plate c', the raised and depressed portions of the rolls c and d impressing themselves upon the surface of the can. The gear H being at least twice the diameter of I-I, at least two full revolutions of the rolls c and d will occur to one revolution of H. The cutting, beading, and impressing of the can will take place during one revolution of the rollsc and d, and during the second or alternate revolution the can will be raised out of contact by the engagement of the circumferentialcam h with the roller h. During the first part of this open position of the rolls c and d the side cam h2 will come in contact with the cam-roller t' upon the lever I. Thus through its connection z" and lever J the collarK is moved outward and forces the iinished can from o the roll c. During the remainder of the same revolution a second can or a further portion of a cylinder is shoved on the roll c and the described operation is repeated. Y

It is obvious that many changes may be made in form, proportion, and arrangement of the various parts without departing from the essential character of the invention. I

therefore do not desire to confine myself to the particular form or arrangements of the parts herein shown; but

What I claim as new, and desire to secure by Letters Patent, is
